When I was in school, 15 years ago, we made chess pieces turned out of aluminum and the chess board on the mill. Each student had to CAD design and hand program the board and chess pieces, pictures for reference.
Then for 3D milling, we had to make a simple mold out of a block of aluminum, had to pour RTV silicone and the part had to be exactly what was drawn on CAD, again, up to the student to design.
But the standard manual machining first.
Just idea's.
